The "due on sale" clause (DoSC) obligates the seller to notify the lender if the property is sold.Failing to do so would place the seller in violation of this agreement, giving the lender the right to accelerate the loan.But no laws are being broken here.So, subto is neither legal nor illegal.Second, it only works because most lenders are more interested in receiving payments than in invoking the DoSC clause and foreclosing on the property.But, it can work, provided seller and buyer are both on board and the proper process is followed.
